To all whom it may concern:

Be it known that T, PERLEY R. Grass, a

citizen of the United States, residing at panying drawings, is a specification, like letters on the drawings representing. like parts.

My invention relates to loading mechanism employed in connection with hand tack.- ing devices most commonly employed in lasting boots and shoes.

The type of loading machine to which my invention more particularly relates is that wherein the loader and the hand tacker are both provided with raceways, fitted at their adjoining ends with couplin devices by which they maybe couple together to form in efl'ect one continuous raceway extending from the loader to the hand tacker.

My invention comprises improvedmeans for guiding and coupling the two raceways together as they are brought into cooperatingrelation, and other features to be hereinafter referred to.

When the tacker is detachedfor use, its raceway part is removed with it and en lies the tacks for a limited use of the tee s uring which time the hopper or loader racewa is being filled with tacks. When the tac er raceway is exhausted it is coupled to the loader raceway and the tacks reviously loaded therein slide in a bod own into and fill the tacker raceway, whic ma be again removed for use.

the hopper on line 3-3, Fig. 1,

clutch members 01 and 0? having secured" thereto respectively bevel gear d and the pulley d the latter equipped with a shipg per d. The pulley d isbelted to any suitable source of power. The bevel gear 03 meshes with gear d fast on a shaft 03 see Fig. 4, supported in a bearing (i at the top of said postb', and to the other end of said shaft (2 is secured a gear d (Fig. 4)" which in turn meshes with the larger gear 03 secured to the end of ashaft e, Figs. 1 and 3, running in bearings e and 6 see Fig. 1, formed in the sidebf the hopper 6 To the opposite rear endof the shaft e, Fig. l, is secured the gear 7 in mesh with the gear f on the end of "the lifter shaft g, mounted in bearing 9 in the rear wall of the hopper. To the inner end of this. shaft 9 is secured the tack lifter wheel it, in the inside rim of which are provided the pockets 71., Figs. 3 and 4, having openings if, in the front of the wheel and at If, on the back thereof, the 7 top and bottom walls of said pocket opening end of a raceway j, which is secured to the postb, and extends into the hopper and close to thetack lifting wheel h, F 4. Through this opening in the ,front 0 the hlppiper extends the reduced inner end of the s a ing disk \k, provided with narrow circumferential wings Z, one of the ends of which are secured tov the disk, the other ends being free and slightly sprung-inward so that as the disk revolves the wings will brush any improperly positioned tacks from the top of thefracewayt at, having secured thereto the clear- The raceway j is provided at its top with the slot j through which the'tacks may slide points down, with their heads resting upon the sides of the raceway, protected by the cover j secured to the said sides by brackets j and screws j, see Fig. '1.

he tacks in bulk are placed in the hopper from which they are lifted by the lifter and deposited on an inclined table It down which they gravitate to the upper end of the raceway. Such tacks as may, fall point first into the raceway, all others being brushed aside by the clearer wheel is.

As stated the raceway is in two parts 7 and i one part 7' being secured to the post b and the other to the removable tacker m,

Fig. 1. The two adjacent ends-of the two parts of the raceway are provided with coupling members as follows: The part j is provided on its under face with a table or rest a, secured thereto by screws a, said rest being slotted longitudinally and obliquely through its center as at .0 in dotted lines, Fig. 6, to receive the spring locking member 0 adapted to enter a V-shaped slot 0 in the under side of the part 3' of the raceway. The removable raceway part 7' is provided on its opposite sides with the spring coupling members, p having on their inner faces, at their ends V-shaped lugs i (Fig. 5) adapted to enter similarly shaped depressions (Fig. 7 in the sides of the part 7'. Cooperating with the coupling members p and to hold them down in proper position are the lugs 11) one on each side of the stationary part j.

The coupling members described provide a sure and readily manipulated means for coupling the abutting ends of the two parts of the raceway when brought together end to end and the parts may be readily unlocked by a straight outward or downward pull upon the part j". As will be seen, when the abutting aces of the raceway sections are brought into proximity, the outwardly inclined ends of the lugs j, by engagement with the sides of the part 7', guide the sections into transverse alinement, while the lugs p, by engagement with the members 7, force the part 7' into engagement with the supporting lug p thereby bringing the sections into vertical alinement. The lug p therefore, besides supporting the movable part or section when the parts are coupled together, cooperates with the lugs p in bringing the parts into alinement, while the lugs j perform the dual function of guiding the parts into alinement and locking them in operative position. This is a more convenlent form of coupling than heretofore largely used and requiring a more or less unnatural swinging movement. While I have here and may be discarded without impairing the efficiency of the coupling means shown.

Each part of the raceway is supplied with a spring actuated bevel ended gate, q, pivoted at 7' to a boss 1" on the side of the raceway. Around each pivot r is coiled a spring 9*" which allows the gate to be forced outward when the two ends of the raceway are brought together and which at once closes the gates across the ends of the raceway when the two parts are uncoupled thus preventing the escape of tacks from the raceway.

As the lifter wheel revolves through the mass of tacks at the bottom of the hopper the tacks in quantities fall into the pockets h and, owing to the inclination of the walls of the latter, tend naturally to slide toward the front openings, being however prevented from falling out thereof by the guard wall 8 (Fig. 4) which coversthe front of the wheel to the height of the tops of the pockets. Toward the right hand side of the hopper,

Fig. 3, looking from the rear said guard wall rises in a semi-circular form as at s to'such point that when the tacks are allowed to fall out from the pockets they may be directed into the mouth of the raceway j by the inclined slide or table 7222. As the tacks gravitate into the mouth of the raceway many of them naturally arrange themselves properly in the raceway with their heads resting on the top edges of the sides thereof and their points depending in the raceway. The tacks that do not arran e themselves in this manner fall off or arelirushed from the raceway by the wings Z of the clearer disk 70. The tacks slide down the raceway and, being prevented from escaping by the gate q closing the lower end of the raceway, fill the latter, all tacks elevated while the raceway is full falling back into the hopper. Should any tacks chance to fail to fall out from the pockets until the latter have passed the mouth of the raceway and are descendin again into the hopper, said tacks will be directed by the inclined table 1) (Fig. 3) back into the hopper.

When it is desired to refill the tacker it is presented and coupled as described to the all tacks in the raceway j gravitate at once down into the tacker raceway, this continuing so long as the tacker is coupled to the loader. When the tacker is removed for use the loader continues to fill its raceway lower end of the raceway on the loader when tacker, a two part race-way comprising an mg depression in one part and a cooperatj, movable part into endwise contact with the.

. upper, stationary and downwardly projecting part and a lower movable art, and locking and unlocking means act-mg automatically to lock said parts upon bringing said 5 movable part into 'endwise contact with the stationary part. by an upward-and forward movement and releasable by a direct down= ward and outward pull on said movable part, saidlocking means comprising a looking locking member upon the other part.
